The L-PCX138 is a 15 mm diameter Plano-Convex lens, sourced from the renowned optical vendor, Ross Optical. This lens is specifically designed for use in optical systems that require a convex lens with a flat plane on one side. The lens is uncoated, which means it does not have any additional layers to protect the surface or modify its optical properties.
The lens has an effective focal length (EFL) of 40mm, which is the distance from the lens's center to the focal point when the lens is imaging an object at infinity. This makes it suitable for applications that require a moderate level of magnification.
The geometry of the lens includes a thickness of 1.6mm at the edge and 3mm at the center. The radius of curvature (R1) is 20.672mm, and the back focal length (BFL) is 38.02mm. The lens is made from N-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility.
This lens is designed to work with light of wavelength 587.6nm, which is in the yellow-green part of the visible light spectrum. It is spherical in shape, meaning it has the same curvature throughout its surface. This shape is common in optical systems due to its simplicity and wide range of applications.
